• Provide senior leadership in setting the technical direction for migrating from SAP ECC to S/4HANA, ensuring integration aligns with security, scalability, and "Clean Core" best practices.
• Design and manage the overall integration strategy for S/4HANA migration projects, including defining future‑state architectures.
• Make critical decisions on migration approaches such as greenfield or brownfield, ensuring all integrations adhere to enterprise‑wide standards.
• Develop integration strategies encompassing SAP BTP, external systems, and legacy environments to support hybrid landscapes.
• Lead key architectural choices, including phased transitions, coexistence models, and selection of middleware platforms.
• Establish and maintain standards for interface development in line with SAP best practices.
• Analyze existing ECC customizations and design migration strategies to minimize technical debt.
• Collaborate with business and functional teams to translate complex business requirements into robust technical solutions.
• Anticipate technical risks and develop mitigation plans for challenges related to data harmonization, system consolidation, and interdependencies.
• Demonstrate strong expertise in SAP BTP, SAP PI/PO, APIs, OData, and Event Mesh.
• Apply knowledge of architecture frameworks such as TOGAF with proven experience in landscape rationalization.

Qualifications

• At least 10 years of experience in SAP architecture, with a minimum of 3 years dedicated to S/4HANA migration projects.
• Proven experience designing and leading SAP ECC → S/4HANA transformations (greenfield/brownfield/selective data transition).
• Strong understanding of S/4HANA core concepts (digital core, extensibility, clean core approach, integration strategy).
• Strong experience with SAP Integration Suite (CPI) and integration patterns.
• Working knowledge of SAP PI/PO (for legacy estates and migration planning).
• Expertise with SAP integration technologies and protocols: OData, REST, SOAP, RFC, IDoc, EDI, proxy services, file‑based integration.
• Ability to define end‑to‑end enterprise integration architecture across SAP and non‑SAP applications (CRM, eCommerce, ERP, PLM, HR, Finance, Data platforms).
• Expertise in integration patterns: canonical model, anti‑corruption layer, orchestration vs choreography, sync vs async design.
